Ludlum 12-4-7 Dose Conversion

This area is for discussions involving any fusion related radiation metrology issues. Neutrons are the key signature of fusion, but other radiations are of interest to the amateur fusioneer as well.

Ludlum 12-4-7 Dose Conversion

Post by Joe Gayo »

A have a calibrated Model 12-4-7 placed equidistant (and equal angle to my cylindrical systems) between to fusors to compare NPR. This arrangement is allowing me to compare performance of various modifications.

I would like a second check of my method for converting the dose read out to NPR. The detector is 82 cm from the centers of my fusors (and 15 degrees off-axis, the two devices and detect form a triangle). If the indicated dose is 32 uSv/h (3.2 mRem/h ?), then the NPR is 2.1E+6 n/sec. I used the gammaspectacular.com calculator and set # to 32, #/mRem to 10, cm to 82, and s to 3600.

Thanks.
